"The mathematics of quantum theory has something to say about the nature of human thinking. (...) “Quantum” mathematics really isn’t owned by physics at all, and turns out to be better than classical mathematics in capturing the fuzzy and flexible ways that humans use ideas. “People often follow a different way of thinking than the one dictated by classical logic,” “The mathematics of quantum theory turns out to describe this quite well.” (...) People aren’t logical, at least by classical standards. But quantum theory, Aerts argues, offers richer logical possibilities. (...) “Quantum probabilities have the potential to provide a better framework for modelling human decision making,” (...) “The structure of human conceptual knowledge is quantum-like because context plays a fundamental role,” (...) How search engines retrieve information. (...) “We often rely on hunches, and traditionally, computers are very bad at hunches. This is just where the quantum-inspired models give fresh insights.” (...) Quantum operations in semantic Hilbert spaces are a powerful means of finding previously unrecognised associations between concepts. This may even offer a route towards computers being truly able to discover things for themselves. (…)" - Amira

"Why should quantum logic fit human behaviour? The reason is to do with our finite brain being overwhelmed by the complexity of the environment yet having to take action long before it can calculate its way to the certainty demanded by classical logic. Quantum logic may be more suitable to making decisions that work well enough, even if they’re not logically faultless. “The constraints we face are often the natural enemy of getting completely accurate and justified answers,” (...) This idea fits with the views of some psychologists, who argue that strict classical logic only plays a small part in the human mind. (...) Much of our thinking operates on a largely unconscious level, where thought follows a less restrictive logic and forms loose associations between concepts. (...) This is not to say that the human brain or consciousness have anything to do with quantum physics, only that the mathematical language of quantum theory happens to match the description of human decision-making. (...) To be human is to be quantum.” - Amira
